Eco-friendly biopolymer herbicide encapsulation technology
An innovative herbicide encapsulation technology using eco-friendly biopolymer formulations. This approach enhances herbicide effectiveness by ensuring controlled release, reducing environmental impact, and improving delivery efficiency, with applications in agriculture.
Overview
This innovative technology utilizes eco-friendly biopolymer formulations to encapsulate herbicide active ingredients. The encapsulation significantly enhances the effectiveness of herbicides by providing controlled release and reducing environmental impact. It minimizes degradation through photolysis, leaching, and volatilization while ensuring a more targeted application. This eco-friendly approach results in a cost-effective solution for agriculture and promises faster regulatory approval due to its favorable environmental profile.
Technical specifications
- Encapsulation Technology: Utilizes biopolymers to encapsulate active ingredients, enhancing stability and delivery.
- Minimized Environmental Impact: Reduces photolysis, leaching, and volatilization, ensuring a more targeted application.
- Applications: Suitable for managing challenging weed species, with ongoing trials for imazethapyr in soybeans and imazapic in sugarcane.
- Patents and Trials: Four patents filed for individual active ingredients and one for a herbicide mixture. Carryover tests on corn and rice have shown a 50–70% reduction in phytotoxicity.
Technology readiness level
This technology is at TRL 5, with ongoing validation efforts to expand the platform for various active ingredients. Future plans include achieving nanoscale particle sizes and further trials on non-tolerant crops.
